Application filed December 29,1913. Serial No. 809,414.

To all whom it may] concern Be it known that I, TOMAS FRED HOUSE, a citizen of the UnitedStates, residing at Hurst, in the county of Texas and State of Missouri, have invented certain new and useful Improvements in Hay-Stackers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in hay stackers and more particularly to those employing a stacking head or fork and means for raising said fork to an uprightposition.

The primary object. of the invention is to provide a stacker of this type with im proved means for imparting a return movement to the stacker head after the same has been raised to an upright position.

A secondary object is to provide means for applying a braking action to the supporting wheels of the stacker simultaneously with imparting the above mentioned return movement to the stacking head.

lVith the above objects in view, the invention resides in certain novel features of con struction and combination herein described and claimed and shown in the accompanying drawings wherein Figure 1 is a side elevation of my improved stacker; Fig. 2 is a plan view thereof; and Fig. 3 is a detail vertical section on the-line 3-3 of Fig. 1.

In the embodiment illustrated, the stacker comprises in general, a supporting frame 1, arms 2 pivoted to one end thereof, a stacking head or fork 3 carried by the outer ends of said arms, an A-shaped hoisting frame 1, a cross head 5 carried by said A-frame, connections 6 between one end of said cross head and said arms 2, a block and tackle mechanism 7 for actuating said hoisting frame, and flexible cables 8 connected to the fork 3 at one end and having yielding connect-ions with the frame 1 at their opposite ends.

Coming now more particularly to details of the present invention and parts closely coacting therewith, the supporting frame 1 comprises longitudinal'side bars 9 connected at their opposite ends by transverse bars 10, said side bars 9 being provided with openings in which a supporting shaft 11 is rigidly secured.

The lower ends of the side bars 12 formof said hubs, are sleeves l5 slidably mounted on the shaft 11 said sleeves being provided with guide pulleys 16. Coiled springs 17 encircle the shaft 11 between the sleeves l5 and bear at their opposite ends on the sleeves 15 and within socketed slides 18 mounted on theshaft 11 near its center.

The socketed slides 18 above referred to,

are provided with lateral ears 19 to which are fastened the inner ends of chains 20 which lead from said ears under the guide pulleys 16 and are then connected at a suitable pointto the flexible cables 8, said cables extending forwardly and being secured to the opposite ends of'one of the supporting bars 21 of the fingers'QQ forming the tines of the fork.

In the operation of the device, when hay has been loaded onto the stacking head or fork 8, the blockand tackle mechanism 7 may be actuated in any suitable way to rock the A-frame 4 around the shaft 11 and by this operation the arms 2 of the fork 3 will be swung around their pivots 2 until they assume a position past a point directly above said pivots. By the time the stack ing head has reached this position, the cables 8 will have drawn the chains 19 through the guide pulleys 16 thus compressing the springs 17, the force of which is now exerted to return the stacking head to its normal position.

By the disposition of the springs 17 and their coacting parts, it will be clearly seen that when the stacking head is raised, the socketed slides 18 will be moved by the action of the cables 8 and the chains 20, to compress said springs 17 against the sleeves 15 and force said sleeves into frictional contact with the inner end of the hub of the wheel 14: and said hub will then be clamped between the fixed stops 13 and the sleeves 15. I consider this a very important feature of my invention since the momentum of the stacking head 3 in returning to its normal position is imparted to a great extent to the mentioned positioning of parts, any move-- ment on their part is impossible.

Although I have described my inventionv with considerable minuteness, I do not wish to be limited to details other than those amplified in the appended claims.

VhatI claim as new isz 1 Ina hay stacker,the combination with a supporting frame having a transverse shaft, armspivoted to said supporting frame, afork carried by said arms,-a hoisting frame, means for actuating the same, and aconnecting elementbetween said'hoistingframe-and said pivoted arms, of a coiled spring slidably mounted on said transverse shaft and havlngone GHd fiXGCL-EL guide carriedby the supporting frame, and a flexible connection secured to said fork, passing through said guide, and secured to thefre'e end of said c'oiled spring.

2. In-a hay stacker, the combinationwith a supporting frame having transverse shaft, arms pivoted to said supporting frame, afork carried by said arms, ahoisting frame, means for actuating'the same, and a' connecting element between said hoisting frame and said'pivoted arms, of a-fixed stopcar' ried by said transverse'sha'ft, a supporting? wheel having its hub journaled on' said shaft, and bearing against said stop, .a sleeveslid ably mounted on said shaft and bearing against the opposite end :of'said hub, a guide on said sleeve, a spring slidably mountedon' said shaft and hearing at one end against said sleeve, and a flexible connection secured to said fork and the free end of said spring ;and passing through the guide of said sleeve.

3. In a hay stacker, the combination with a 7 supporting frame having a transverse shaft, a sleeve slidable on said shaft, a guide onsaid'sl'eeve, arms pivoted to said supporting frame, a fork carried by said arms, a hoisting frame, means for actuating the same, and-a connecting element'betweensaid hoisting frame and said pivoted arms, a spring loosely coiled around said shaft and bearing'at one end against said sleeve, and a flex'ible connection secured'to said fork and the free end of said spring and passing through the guide'of said sleeve.

4. Ina hay stacker, the combination with a wheel supporting frame and a movable lifting member carried thereby, of amovable braking element normally out of engagement with the supporting" wheel of said frame, an operatingelement carried by said lifting member, and a yielding connection between said operating element and said braking: element for impartinga return movement tosaid lifting member when raised and for simultaneously releasing'said braking element. v

In testimony whereof I have hereunto set my hand in' presence of two subscribing witnesses.
